the simple answer is there are probably very few times that these gyms are only hosting single matches at a time. So in order to use the space efficiently you set up 3-4 courtS at the same time. And that makes it nearly impossible to shoot video from the side. Hence the end line shot.
Fuji TV can at least put the popular teams on the outside for recording or broadcast. As tournament gets to qf then you can shrink to 2 courts.
I've always wondered if the Cameras belong to the Gym or if the broadcasters bring their own cameras. Not to mention the lighting. A lot of these matches are played in the same gyms across the spectrum of HS, Uni, V9, V1, V2 but the quality varies greatly (not to mention how extremely poor the VTV broadcasts are).
It's oddly coincidental to me that those 2017 V2 (Forest Leaves) matches had good quality (and commentary) and these 2017 V9 matches had quality, and then it stopped. I assume it's budgetary? But ... coincidentally ... this is when the JVL announced all their "Grow the Game" stuff. Maybe they think lowering the quality of broadcasts will encourage people to go see them live, sort of like NBA blackouts. The experience of this fan in San Francisco is probably not their priority
